Facades
Facades can be used to make your base appear cleaner. They can cover up both sizes of cable, and they may be made out of many kinds of blocks.

Although facades can cover all sides of a cable, subparts and cable connections are allowed to protrude though.

Be clever with them to improve your base aesthetic or make blocks with different textures on each side.

Hiding Facades
Facades will be hidden while holding a Network Tool in either hand.
You can interact with blocks behind hidden facades without having to remove the facades first.
Recipe
To make a facade with the texture of a block, place that block in the middle of 4 Cable Anchors.
